Welcome to the Manufactured Home Ownership information page.

Effective May 1, 2005, responsibility for maintaining ownership and siting information for manufactured structures transferred from the Department of Motor Vehicles (DMV) to the Building Codes Division (BCD). Homeowners and other interested parties should no longer contact DMV if they buy, move, or otherwise change the status of a manufactured home or other manufactured structure. Instead, most transactions will now take place at the county assessor’s office, which will be acting on behalf of the division.

For EXEMPT homes, contact the county where the homes is sited for current information.

To make changes to a manufactured home, you MUST contact your county taxation/assessment office to have these changes processed. The Building Codes Division will not process transactions unless they have been first submitted to the county taxation/assessment office and have been refused. Click on the County Offices link below for contact information for each county assessor's office. For information, please call 503-373-1309.
